Abstract: Impact stresses which result from breaking of an electrical transmission line, under a shock load, act to break post insulators which support the line and are secured to supporting poles. The shock load is controlled effectively by supporting proximal ends of the post insulators for pivotal movements through arcuate paths of travel about axes which extend upwardly and outwardly from their respective poles, whereby the shock load is converted into rotary motion and the weight of the line works to dampen the shock load. The pivoting movement is achieved by means of compact, sturdy, inclined hinge assemblies connected between the poles and the proximal ends of their respective post insulators.
